SPECIFICATION forming part of Letters Patent No. 366,248, dated July 12, 1887.

Application filed December 8, 1886. Serial No. 22l,089. (No model.)

To all whom, it may concern:

Be it known that I, JACOB S. PEAOOGK, a

citizen of the United States, residing at the city of Lancaster, county of Lancaster, State of Pennsylvania, have invented a new and useful Improvement in Traction \Vheels, of which the following is a specification.

Thisimprovement is applicable to the wheels of ordinary draft or steam propelled wagons, or to special wheels constructed for the same.

The object of the improvement is to simplify the construction and reduce the cost of the same, and in their use to save wear and expense of haulage, while increasing the tractive power of the animals or steam-drag at tached to the wagons provided therewith.

The drawings herewith will give an expert a clear comprehension of my improvements, like letters of reference indicating like parts. Figure 1 represents in full front elevation a view of my preferable style of wheel; Fig. 2, a plan on the line a a of Fig. 1, showing the saddles and shoes in section; Fig. 3, a detached shoe in side elevation; Fig. 4, a plan of the same; Fig. 5, a front and side elevation of-the dustguard and shoe locking plate; Fig. 6, a front, plan, and side elevation of the shoesaddle; Fig. 7, a full front elevation of an al ternative Wheel provided with tension spring pockets; Fig. 8, a plan on the line a a of Fig. 7, part in section; Fig. 9, a front elevation of a detached shoe with its tension-spring-pocket connection and dust-guard in place; Fig. 10,

a plan of the same; Fig-11, an elevation of the shoe, showing the bifurcated opening for the saddle-pin, the dust-guard ledges, and securing-bolt holes; Fig. 12, a detached front and side elevation of the dust-guard plate, showing the lock for the saddle-pin; Fig. 13, a front elevation, plan, and end view of the saddle.

In the drawings, A represents the wheel rim; A, the tire; A the spokes; A the hub; B, saddles in number equal to the shoes to be applied to the wheel, having ears B, which pass snugly over the wheel-rim and are provided with pivotal pins 13 east integral there with or suitably secured thereto. Lugs B, with bolts B, serve to secure the same in place.

Shoes 0, of a length adapted to the wheel, have sides 0, admitting of free movement of the wheel between, are recessed at the center 0 so as to clear the ears of the saddle B, and are notched or bifurcated at C, so as to admit of being passed over the periphery of the wheel upon the pins B of the saddle. A portion, 0, projected beyond the recesses 0 is provided with undercut or beveled ledges 0 within which dust-guards D, provided with keeper-lugs D, are fitted. Said lugs entering within the-top of the bifurcation C of the shoe, and bolts or rivets being introduced in the holes 0 D after the shoes are in place also internally threaded, and bored at G to suit the spring compressing-rod H, completes the springease. A red, H, having a crossarm, H, bored to suit the pin-connection with thedust-guard, is adapted to slide freely in the bore G of the cap G, has its inner end provided with a washer, H, of a diameter permitting its free movement in the barrel G, and a wire coiled spring, I, is constructed to occupy the entire space between the washer H and cap G. Vhcn the head F and cap G are in their normal positions, the case or pocket G merely gripped at each end, the ten sion of the spring I is increased or diminished by screwing the barrel into the head F and screwing up the cap G upon the same, thus decreasing the length of the barrel or pocket and increasing the compression of the spring and its pull upon the rod H and the shoe-plate, to which it is connected by a pivotal bolt, H. Saddles B, with ears B and shoe pivotal pins B, are secured upon the inner face of the rim of the wheel by bolts B.

Shoes J, adapted to the wheel, are provided with sides J, and recesses J at the center of the same, to clear the saddleears B. They are notched or bifurcated at J to admit of being slid upon the plus B of the saddles B, and are bolt or rivet holes J provided with bevel undercut ledges J and Fitted to the beveled ledges are dust-guards K,having keeper-ledges K, adapted to enter the top of the bifurcated notch J, with bolt or rivet holes K, and an extension or arm, K, with pivot-hole K, whereby the cross-arm H of the rod H is con nected with the arm and shoe pivotal bolt H passing through the same.

To apply the improved shoe after the saddles B have been secured in place, the shoes are lifted and placed upon the periphery of.

the wheel, with the pins 13 of the saddles within the notches C or J of the shoes. The dust-guards D or K are then slid into their places in the undercut slides C J, and are permanently or removably connected with the shoes by using either rivets or bolts in the holes 0 D or J K", as the case may be. In the first wheel this completes the attachment. In the second wheel a pivotal pin, H is passed through the extended arm K and cross-arm H of the spring pocket and completes the connection with the spring-pockets swinging central to the wheel upon the clampingbolts E.

Having disclosed my invention, shown its application, detailed its construction and use, I desire to claim as follows:

1. As an improvement in traction-wheels, a saddle, B, adapted to be applied to the inner face' of the rim, having ears B and pivot-pins B cast or formed integral therewith, said ears clasping the sides of the rim between the same and removably secured to the rim by bolts 13, in combination with the slides D and shoes 0, as shown, and for the purpose set forth.

2. As an improvement in traction-wheels provided with saddles, as shown and described, shoesO, having side flanges, G, recessed at their centers 0 to clear the saddles B, a raised portion, G, with bifurcated notch 0 beveled slides 0 and securing-holes C, in combination wit-h the pins B of said saddles, and a dust-guard and locking-plate, substantially as and for the purpose set forth.

3-. As an improvement in traction-wheels, the combination therewith of the shoes by saddle pivotal pins B", removably locked thereon by the bifurcated notch 0 and keeper-lug D of the dust-guards, secured in the slides G by bolts or rivets in holes 0 D substantially as set forth.

at; As an improvement in traction'wheels, the combination therewith by annular plates E and pivotal clamping-bolts E, of transverse central spring-pockets havingheads F, adapted to pivot or vibrate upon said clampingbolts, a coiled spring, I, and washer H sliding free in said pockets, secured to a rod, H, having cross-arm H, connected with dustguard locking-plates K by pivotal bolt H with shoe J by bolts or rivets in holes K' J, substantially as and for the purpose described.

5. In combination with the shoes of a traction-wheel,provided with central spring-pockets, as shown and described, thedust guards and locking-plates K, having keeper-lugs K, adapted to enter the bifurcated notch J of said shoes, an eXtension-arm,K connected with the cross-arm H of the spring-pocket rod H by pivotal bolt H ,'the sides of "the dust-guard plates fitted to slide in the undercut ledges J*, and removably secured in place by bolts or rivets in holes J K", substantially as and for the purpose set forth.
